[PATCH] driver core: Use system_percpu_wq instead of system_wq

[Nathan Chancellor]

Commit 1137838865bf ("driver core: Use mod_delayed_work to prevent lost
deferred probe work") added a use of system_wq, which is deprecated in
favor of system_percpu_wq added by commit 128ea9f6ccfb ("workqueue: Add
system_percpu_wq and system_dfl_wq"). An upcoming warning in the
workqueue tree flags this with:

  workqueue: work func deferred_probe_timeout_work_func enqueued on deprecated workqueue. Use system_{percpu|dfl}_wq instead.

Switch to system_percpu_wq to clear up the warning.

Fixes: 1137838865bf ("driver core: Use mod_delayed_work to prevent lost deferred probe work")

This should go via the driver-core tree since the Fixes commit is only
in that tree currently. The warning is only visible in -next when the
driver-core tree and workqueue tree are merged together.
